Note the polarities when installing batteries. Do not short-circuit the positive and
negative poles of the same battery or battery string. Otherwise, the battery may be
short-circuited.
Check battery connections periodically, ensuring that all bolts are securely tightened.
When installing batteries, do not place installation tools on the batteries.
Battery Short Circuit
Battery short circuits can generate high instantaneous current and release a great amount of
energy, which may cause equipment damage or personal injury.
To avoid battery short-circuit, do not maintain batteries with power on.
Flammable Gas
Do not use unsealed lead-acid batteries.
To prevent fire or corrosion, ensure that flammable gas (such as hydrogen) is properly
exhausted for lead-acid batteries.
Lead-acid batteries emit flammable gas when used. Ensure that batteries are kept in a
well-ventilated area and take preventive measures against fire.
Battery Leakage
Battery overheating causes deformation, damage, and electrolyte spillage.
When the electrolyte overflows, absorb and neutralize the electrolyte immediately. When
moving or handling a battery whose electrolyte leaks, note that the leaking electrolyte may
hurt human bodies.
If the battery temperature exceeds 60°C, check for and promptly handle any leakage.
Electrolyte overflow may damage the equipment. It will corrode metal parts and boards,
and ultimately damage the boards.
If the electrolyte overflows, follow the instructions of the battery manufacturer or
neutralize the electrolyte by using sodium bicarbonate (NaHCO
3
) or sodium carbonate
(Na
2
CO
3
).
